Waste Division

On April 10, 2023, the public comment period begins for proposed cleanup activities for Leaking Underground Storage Tank (UST) case numbers 3281.03, -.04, -.06 at Pilot Travel Center #328 in Quartzsite, Arizona. The comment period ends May 10, 2023.

Public Notice Information

A Corrective Action Plan (CAP) dated Jan. 27, 2023, has been submitted to ADEQ. The CAP contains a proposal to clean up petroleum contamination from a UST system at the following facility:

Leaking UST Case File No.: 3281.03, -.04, -.06
Facility ID No.: 0-006588
La Paz County

Facility Address

Pilot Travel Center #328
1201 W. Main Street
Quartzsite, Arizona 85346

Proposed Activities

The proposed activities include the following cleanup technologies that will be used to obtain the cleanup levels that are protective of public health, welfare and the environment:

Air Sparge and Soil Vapor Extraction (AS/SVE) and Monitored Natural Attenuation (MNA): Contaminated soil and groundwater will be treated using an AS/SVE system. An AS/SVE system injects air (sparged) into the groundwater to volatilize contaminants in groundwater. The vapors generated from sparging are subsequently extracted from the ground with the SVE system. The vapors will be treated before being emitted to the atmosphere so that emissions do not exceed levels specified in any air quality permit issued by the county, city or state. An MNA program will be implemented, if necessary, after the AS/SVE system is shut down to periodically monitor the natural processes that reduce contaminant levels in groundwater.

In-Situ Chemical Oxidation (ISCO): Contaminated groundwater will be treated using ISCO by injecting a hydrogen peroxide-based product into the affected well(s) and directly into the formation. ISCO breaks down petroleum related chemicals of concern (COCs) through abiotic chemical oxidation reactions.

Solar Sipper Liquid Non-Aqueous Phase Liquid (LNAPL) Recovery System: is a solar powered remediation system, designed for remote applications where electrical power is either not available or not economically feasible. This uniquely flexible system can be configured for up to eight wells. The compact, easy to install features make this unit efficient to move and implement multiple wells. The Solar Sipper uses a downwell pump to recover hydrocarbons through a floating oleophilic/hydrophobic intake filter. Once the pump canister is filled via the vacuum cycle, the pump reverses, pressurizes the system and pumps the recovered fluid to the surface and into a storage vessel.
